Sorry, for late answer, I couldn't join last week, I can join today if needed.
I saw your audit which is very descriptive, that helps with understanding it.
Thanks! As I understand you would like to fix the drivers ,which broke
the R2 handling considering RX Ring Full rule.
I can send fix proposal for mlx5 driver. if so should I create another patch
from scratch and link that conversation only?
Regards,
Marcin
